JOHNSON, OF COLUMBUS, OHIO, ASSIGNOBS 'IO THE BUCKEYE AS'IIEEZI; -('IASIINGS COMPANY, 0F COLUMBUS, OHIO Application lcd February 3, 1928. Serial No. 251,629f* This invention relates to improvements in car trucks,-one object being to provide a' simple and eilicient truck construction in which the dismembering and 11e-assembling 5 of the truck shalll be facilitated when the making of repairs render desirable the ready ing an embodiment of our invention;

Figure 2 is a view partly in plan and partly in transverse section; Figure 3 is a vertical transverse' section through the side -ra-me, the bolster being shown in elevation,and

Figure 4 isa plan view of the bolster. -v

The side frame comprises an upper or compression member 1 and a lower or tension member 2,-'the central portion ofthe late ter being provided with lateral extensions 3, 4 to extend the spring' seating capacity of the structure. The side frame alsoI comprises columns 5, 5, suitably-spaced to deine VN.a central-opening for-the accommodation of the bolster 6, the spring plank 7 and springs 8, 9,-the bolster being provided at each end` with an extension 6 to enlarge the spring seating capacity of said bolster, The springs 8 are seated at their upper endsagainst the bolsterl and at their lower lends upon the spring plank, 7, while the springs 9 are seated at their upper ends againstv the boltserl and rest at their lower ends on shelves 10 inte al w1th the-side frame and partially upon ra1sed seats 11 on the s 'ring plank 7.

The outer'we s 12 at the u per portions set. relatively showing a portion Figure 1 is a view in elevation illustrat- .with the notches 20 at the upper portions of Awebs entering 'between the stop sho), ders and to the inner Webs 13 and relatively to the intermediate webs 14 so as to present an approximate Z-shape in cross section and said Webs 12 and 13 may be provided at their free edges with ribs 15, 16. r

vThe bolster 6 is provided near each of its ends and at respective sides with laterally projecting enlargements 17 forming shoulders 18 to cooperate with the offset webs 12 of the side frame columns and thus form inside stops for the side frame. The bolster is pro-` vided at each end with integral lugs or keys 19 vwhich project laterally so as tobe disposed in line with the offset webs 12 or the ribs 15 thereon, and thus form outside stops for the side frame. if

Each column 5 is provided above the web 12 withl a notch 20,*below which, the lugsor keys 19 on the bolster are normally disposed.

.In order to assemble or disassemble the side 70 frames relatively to the associated parts of the truck, the bolster with the springs and spring plank will be raised so that the lugs or stops 19 will be brought into alinement the side frame columns, and then the side frame can be moved laterallyto remove it from the truck -or appl it thereto.

Having fully describe our invention what we claim as new and desire to secure by LettersPatent,'is:- y

1. In a car truck, the combination of a side frame having columns spaced to provide a bolster opening, said columns having inwardly projecting webs at their outer edges, a bolster having lateral projections forming stop shoulders cooperable with said inwardly projecting webs, outside stop lugs rigid with thebolster, the'inwardly projectin column 90 stop lugs on the bolster, said columns having webs to permitl passage of said stop lug's notches above said inwardly projecting whenthe bolster is raised and the side frame is moved laterally in assembling thev same on or removing it from portions of the truck strllilcture with which said side frame vnorma Y coo rates. f v

apzar truckfthe combination of a4 side frame having columns wd to provide l v a bolster opening, each column having an in- Wardly projecting web terminating at a transverse notch in the up er part of the column, a. bolster having Smulders forming g, stops, and 'stops on the bolster spaced from the stop shoulders, the inwardly projecting Webs of the columns being received between the stops and the stop shoulders on the bolster wben in normal position. l@ 3. ln a car truck, the combination of a side frame having columns spaced to pro-l vide a bolster opening, the column having opposed notches at their upper ends, a spring plank extending into the bolster opening, springs resting on said plank, a bolster having one of its ends extended throughthe bolster opening and supported by said springs, and oppositely extending'lugs provided on the bolster, contacting directly with said columns and adapted to cooperate with the notches to permit the side frame to be detached when the spring plank, springs and bolster are elevated as a unit.

In testimony whereof, We have signed this specification.
